The purpose of this study was to combine diffusion tensor fiber tracking and 3D deformable histological atlas of the human basal ganglia to build a probabilistic map of cortico striatal connections. Results provide a 3D atlas and connectivity-based segmentation of the striatum. Visualization of cortico-striatal connections allows delineating the sensorimotor, associative and limbic territories of the basal ganglia.
